I am amateur mechanic. I have 1982 Grand Prix with 3.8 v6. I want to use drive train to make t bucket. Can I convert to fuel injection system? What do I do with ecm stuff.
Yes you can convert to fuel injection system. You will need to get all the wiring, ECM and manifold system from a newer vehicle. Or you will need to purchase an aftermarket fuel injection system. Holley makes several fuel injection kits. Holley also offers stand alone fuel injected kits. They claim “anyone can install an EFI in a single afternoon.”
Just depends on your wallet and the end goal.
